2. A radiator including a frame having front and back plates, and aseries of tubes,

having screw-threaded ends, said tubes extending between said plates,and being secured to one of the plates to deliver air through theopenings in said tubes, the connections for said tubes including nipplesfitting the screw threaded ends of t e tubes and having flaredmouths atone end and flared outlets at the opposite ends that open into saidtubes.

line with said pipes, the connections secur- .ing the tubes to the placeincluding nipples fitting said screw threaded ends of the tubes andhaving flared months at their inlet ends and flared outlets at theopposite ends of the nipples that open into said tubes.
